Need to grind samples in the lab without any contamination? This Cole-Parmer agate mortar and pestle set is perfect. The 3-inch size holds about 25 mL, and it's made from natural agate stone – that's a 6.5 on the Mohs hardness scale, so it's really durable. The grinding surfaces are highly polished, which makes cleaning a breeze and helps prevent cross-contamination between samples. It's even autoclavable for sterilization. The whole thing is solid and well-made, though keep in mind the physical dimensions might have a slight tolerance of around ±3mm. Ideal for chemistry, pharmacy, or any lab work where you need pure, uncontaminated results. A reliable, classic piece of lab equipment that gets the job done right.
